AUTOMATIC GATE.

SPECIFICATION forming part of Letters Patent No. 375993, dated January3, 18.88.

Application tiled August 24, 1887.

To aZZ whom it may concern:

Be it known that I, JAMES `ELLsWoRTH GOODHUE, of St. Charles, in thecounty of Kane and State of Illinois,h aveinvented certain new anduseful Improvements inAutomatic Gates; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and tothe letters of referencemarked thereon, which form part of this specification, in Which- Figure1 is a View showing my improved gate and its operating devices. Fig. 2is a plan vlew of the same. Fig. 3 is a detail view'of thepivotedsegment.

Ihis invention relates to improvements in swlnging gates, which can beautomatically opened and closed by means of levers mounted on propersupports at suitable distances from and on each side of the gate, and ofsuitable connecting devices between said levers and the gate,hereinafter described, illustrated in the drawings, and pointed out inthe claims hereto appended.

Referring tothe accompanying drawings by letter, A designates the gateproper,` which may be of any suitable construction, but has its rearupright, a, elongated ,and rising vertically above the top of the gate adistance corresponding to about one-half or two-thirds of the height ofthe gate itself.

B designates the outer gate -.post, against which the gate is closed,and I1 designates the inner gate-post, upon which'the gate A is mountedby means of hinges C, secured to post b and tothe upright c of gate A,as shown. To the upper portion of upright a is secured a bracket, D,which rises to the top of said upright and has pivoted upon it a'segment, E, as shown. Instead of using a bracket, D, the segment may bepivoted upon the top of upright' 1,which may be enlarged to support thesame properly. The segment E is a tlat semicircular disk, and is pivotedat apoint which'would be about the center of the complete disk of whichthe segment is formed. rIhe rounded periphery of said segment isgrooved,for a purpose hereinafter shown. The segment is pivoted in suchmanner that its peri pherylies and moves in a horizontal plane.

Serial No. 247,768. (No model.)

e e designate metallic plates, Which are respectively secured to theupper and under surfaces of segment E,and project slightly beyond thecurved edge ofthe same, so as to increase the depth of the groove onsaid edge and* to protect the segment from wear.

Ff designate pins or arms depending from Segment E, near its outerrounded periphery. rIhe pin F is at about the center of the roundedperiphery ofthe segment, whilepin f is near one corner of the same, onthe side to which the gate turns in opening, as shown. The up right a isrounded at one upper edge to permit free play of the pin F as thesegmentis turned.

G designates a horizontal arm secured to upright a, and standing forwardand outward therefrom in a parallel line with the horizontal bars of thegate. This arm G stands between the pins Ff on the segment E.

H h designate levers pivoted aboutcentrally upon suitable posts or othersupports on each side of the gate, respectively, and about in line withthe upright a thereof, and at such distance from the gate as to permitthe levers to be operated by a person on horseback or in a vehiclewithout danger of the horses being struck by the gate in swinging open.The upper end of lever H is connected loya Wire, I, with the corner ot'segment E nearest lever h, which segment stands normally at right anglesto the gate, with its rounded face inward, the Wire I passing around thegroove in said segmentand being secured thereto by a pin, a staple, orin other suitable manner.

t' designates .a wire connecting the upper end of lever h with thecorner of segment E nearest lever Hand passing around the `groove insaidsegment and secured thereto similarly to the wire I otlever H. rlhe twoWires thus pass each other in the groove of segment E, running inopposite directions. Ihelower ends oflevers H h are connected by a Wire,c, so that the movement of one lever will impart 'a corresponding degreeof movement to the other.

J j designate upright spring catches arranged on opposite sides of thegate, the catch J being arranged to engage a suitable keeper on the postB when the gate isshut, and the catch j being adapted similarly toengage a ICO keeper on a post, L, situated at the side ofthe road towhich the gate opens. The upper end of catch J is connected bya wire, K,with the corner of segment E on the opposite side of the gate, and thecatch j is similarly connected with the opposite corner of segment E bya wire, k, so that the wires K k cross each other, as shown.

The operation of the device is as follows: \Vhen the gate is closed, aperson wishing to open the same and approaching from the side to whichthe gate swings in opening, grasps the lower end of lever h aud pushesit inward toward the gate. This movement of the lever causes segment Eto turn toward the same by reason of wire z', and this turning causeswire K to 'pull back catch J and disengage it from its keeper. Furthermovement ot' the lever lt causes the segment E to turn still more on itspivot toward said lever, and this causes pin F to engage arm G of thenpright a, and consequently the gate to turn and open until its movementis stopped bythe post L and its catch j engaged by the keeper thereon.After passing through the gate, the lever H is operated in the samemanner as described for lever l1, causing the wire I to turn segment Ein the opposite direction. This movement of the segment E tirst causesthe disengagement ofthe eatchj from itskeeper on post L, and causes theengagement of the pin f with the opposite side of arm G, the backwardturning of upright a, and consequent closing of the gate. The pins F fare so arranged relatively to arm G that a slight partial rotation isimparted to segment E before they engage said arms sufiicient to causethe disengagement of the catches and their retainers. To open the gatefrom the side of lever H, the lower end of this lever is pushed outward,causing the already described movement of lever h through wire @,andconsequent open ing ofthe gate. Itis obvious that by the devicesdescribed the catches of the gate are released before any foree isexerted upon the gate to open or close it. The leverage of pins F f uponthe arm G can be regulated by varying their distance from the pivot ofthe segment, as is evident.

Having described my invention, what I claim as new is@n l. Thecombination ofthe gate A, having a rear vertically-extending upright, a,rounded at top, as described, and a horizontal arm, G, secured to thetop of said upright above the gate proper, with the semicircular segmentE, grooved on its curved periphery and provided with thc protectingmetallic plates e e, projecting beyond its curved periphery and pivotedto swing horizontally upon the top of upright a above arm G, the pinsFf, depending from said segment at points respectively near the centerand one corner ofthe periphery thereof and embracing between them thearm G, and the levers H L, and wires I i and c, for

operating said segment and thereby opening' or closing the gate, allsubstantially as and for the purpose described.

2. The combination, with gate A, having a vertically-elongated rearupright, a, by which the gate is hinged to itssupporting-post, thespring-catches Jj on opposite sides ofthe gate, and the arm G andbracket D, secured to the top of upright a, of the semicircnlar segmentE, grooved on its periphery and pivoted on the bracket D of upright aabove arm G, the pin F, depending from the center of the roundedperiphery of segment E, and pinf, depending from one corner thereof,en'ibracing between them arm G, the operating'levers H h, and wires I i,connecting said levers tothe opposite corners ofthe segment Il andresting in the groove of said segment, the wire c, connecting the lowerend of said levers, and the intersecting wires K k, connecting oppositecorners of segment E with catches J j, all constructed and arrangedsubstantially in the manner and for the purpose described.

ln testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
